Kansas prisoner who sued over cancer treatment has died

KANSAS CITY, Kan. (AP) — A Kansas prisoner who alleged in a lawsuit that he was not being properly treated for cancer has died. Attorneys and the family of John Keith Calvin say he died Wednesday at the El Dorado Correctional Facility. In a lawsuit filed last month, Calvin says Kansas Department of Corrections officials had not provided proper treatment for his colon cancer. An emergency court filing asking that he be moved to a hospital was denied. Calvin was convicted of first-degree murder in the 2002 killing of John Coates. He always maintained he was innocent and a co-defendant later said Calvin did not kill Coates. Calvin would have been eligible for parole in May.
